Email was supposed to be dead by now. It isn't.
Email in the Machine Age is a complete guide to email marketing in the era of AI-governed inboxes - where machine learning systems decide what reaches subscribers, engagement signals determine deliverability reputation, and the programs that genuinely serve their audiences earn placement that no amount of technical optimization can manufacture without the underlying substance.
Robert F. Geissler covers the full email program: the authentication infrastructure and reputation dynamics that determine whether email reaches the inbox at all; the AI personalization and content strategies that determine whether it earns engagement when it arrives; the list management disciplines that protect the subscriber relationship quality on which everything else depends; and the measurement frameworks that honestly assess what the program is actually producing - not what the platform reports, but what the business experiences.
Email is the only major marketing channel that is owned, consented, and measurable at the individual level. The AI era has made those properties more valuable, not less. This book shows you how to capture that value.
